Ireland secured a 23-17 victory over Argentina on Saturday as tries from Simon Zebo and replacement Ian Madigan won the series in Tucumán.
The triumph at Estadio José Fierro was not as convincing as last week as Argentina fought until the end, with Madigan's try being the difference.
Jonathan Sexton opened the scoring on five minutes off the tee after number eight Antonio Ahualli de Chazal was caught offside at ruck time.
And the Pumas were struggling to keep offences to a minimum as referee Pascal Gauzère didn't waste time to brandish a card, hooker MatÃas Cortese being shown yellow for no use of the arms in the tackle. The result was Sexton doubling Ireland's lead in the sunshine, with things already looking ominous for the hosts.
That wouldn't prove to be the case though as when Andrew Trimble was shown yellow for taking out a Puma off the ball in a possible try-scoring position, fly-half Nicolás Sánchez stepped up to put his outfit on the board. It was now 3-6 with eighteen minutes played in the second Test.
Ireland did show their quality in attack with a quarter gone when Sexton's cross kick to Zebo led to Lucas González Amorosino getting back in time to ground the wing's chip downfield. It was a warning shot however to the Pumas that Ireland wouldn't be afraid to try things.
The warning was heeded and in fact thrown back in the visitors' court when Argentina chanced their arm from deep, scrum-half Martin Landajo's break leading to Amorosino carrying on the run before recycled ball found JoaquÃn Tuculet for a popular score.
Following the successful extras, Argentina were now 6-10 ahead with 25 minutes played before Irish fly-half Sexton cut the lead to just a point eight minutes from the break.
Sexton had a chance to push Ireland back into the lead three minutes after the break but was off-target as they struggled for any real spell of possession and territory. If they could get good ball one worried for how the Pumas would contain them in the closing stages.
And so that proved as a nice inside ball from Leinster scrum-half Eoin Reddan finally broke the deadlock for the Irish, his pass sending over the poacher Zebo to make it 16-10.
Darren Cave came agonisingly close to possibly putting the result beyond doubt but was pulled up just short when grounding after a strong carry from Rhys Ruddock. Had he crossed, a successful conversion would have put Joe Schmidt's men thirteen points up.
But that mission would be accomplished by Madigan with eight minutes left as his classy try under the posts made it 23-10 before Amorosino crossed with the final play of the game.

A harsh red card for Canada flank Jebb Sinclair soured what was an absorbing Test, but it will be one that the hosts will feel they could have won.
Bizarrely considering there were 73 points last Saturday, we didn't get any at all here until the 53rd minute. Hardly a great advert for the rugby public in this part of Australia.
England had at one point led 10-0, but that felt a long old time ago when they were being battered relentlessly by the All Blacks deep into the second half. The score might have been tight at the final whistle, but England had been blown away by the time Mike Brown and Chris Ashton crossed.
Picking up where they left off against Italy last week, Fiji ran in six tries in Luatoka.
The result follows the Azzurri's loss to Fiji last weekend to round off a poor year in Test rugby so far.
The Scots were dominant, but made rather hard work of their win in the sweltering Houston heat against an Eagles side that is on the up in world rugby.
The result gives Joe Schmidt's outfit momentum going into next week's Test against the same opposition in Tucum�n as they backed up their Six Nations triumph with a solid performance.
The Springboks recovered from a slow start to outscore their opponents six tries to one in an entertaining game in front 30 000-odd fans at Newlands.
France have not beaten the Wallabies in Australia since 1990 and, based on this performance, they are unlikely to change that record in this three-Test series.
Nadolo was one of three try scorers for the Islanders, crossing first before adding two penalties and a conversion after starting at inside centre.
The clock had ticked a minute past full-time with Manu Samoa clinging to an 18-15 lead when Tongan lock Josh Afu was pulled down in a line-out.
Smith's finish in the corner settled a contest in which for 75 minutes the world champions were utterly rattled by Stuart Lancaster's tight-knit squad, who humbled their critics.
Full-back Ayumu Goromaru kicked a total of 18 points, while winger Yoshikazu Fujita seared over for a brace of tries as the Brave Blossoms overturned a 7-0 deficit to blitz their hard-hitting rivals.
It Seven tries, including a double for Mike Brown, saw England finish this year's championship with four wins from five matches and a points difference of plus 73, but eight short of Ireland with Joe Schmidt's side to play in Paris later on Saturday.
It It wasn't pretty and France came mighty close to snatching victory at the end but for a forward pass, but Ireland won't care as they claimed their first title since 2009, a second for most of this squad.
It Hogg was shown red after initially being given a yellow card by referee Jérôme Garcès. Replays duly saw the Frenchman change his mind.
It First-half tries from Danny Care and Luther Burrell gave England the early advantage and they never looked back, keeping the lead throughout as Owen Farrell and Leigh Halfpenny fought each other in a world-class kicking duel.
It The Scots had led through tries from Stuart Hogg and Tommy Seymour to three Maxime Machenaud penalties, before Yoann Huget's interception brought France roaring back into the lead.
It In Brian O'Driscoll's final Test on home soil, the men in green outscored their visitors seven tries to one to further bolster their points difference ahead on next weekend's trip to Paris.
